In January I was really pleased to see that a load of new exchanges had been given RFS dates including my own (list totaled 3035 exchanges). However come February the list suddenly shrunk bank to 2856 exchanges with mine being removed. Today the March list has been posted and we've got 2951 exchanges in the plan (but mine still isn't).

Now I realize that these lists are provisional etc but why were so many exchanges removed between January and February ?
